In this Dec. 5, 2013, photo marijuana matures in ideal conditions at the Medicine Man dispensary and grow operation in northeast Denver.

The Clinic is among the roughly 150 medical marijuana dispensaries hoping to begin selling to recreational users when it becomes legal to sell on Jan. 1, 2014. The state's hopeful pot shops are so mired in red tape and confusion that no one knows yet when or if they'll be allowed to open. Not a single shop will clear state and local licensing requirements until about Dec. 27. (AP Photo/Brennan Linsley)(AP Photo/Brennan Linsley)
